Hi All,

I kind of need some help, the previous owner of my car made a mess of the battery tray when he miss calculated the hole and decided to cut 2 circles next to each other to install his FMIC, so now I've got this giant hole in the battery tray that looks like ass. Furthermore, to make matter worse, he used tin snips on the hot pipe side to fit the home made cooler piping in. It's terrible as you can imagine.

Just wondering if anyone can re-weld up these ass of a holes and re-cut nice perfect circles for me and make it look nice an tidy from top and from below.

I don't mind home jobs as long as it looks good and clean.

If anyone can help and for a reasonable price, PM me...

Cheers,

Johnny

Welding a recutting holes could be a pita.

Have you thought about grabbing a die grinding burr and grind the holes out to the new round (or other) clean shape.

Easy to do and you could even do it with an electric drill instead of a pencil grinder if you don't mind side loading the bearings for a while. Given it is only light plate it shouldn't hurt the drill much if at all.

If you go down this path I would suggest spend a bit of time taping joints etc where the grinds may end up. Once they get stuck in a join etc you will never get them out and they will rust leaving a shitty looking mark.

If the holes work out a bit oversize just make up a rubber sealing gasket or run in some pinchweld edging and make it look like that was how it was meant to be

Well legally tany hole cut in that area must be reinforced to return the rigidity back to that section of the car, so if you are willing to have someone weld in a reinforcement plate that has a clean hole in it then you are also less likely to encounter any stife from it if one day you go to engineer the car.

ok so here is what i would do if i was to keep that piping design.

Remove the pipe, weld in a patch panel of 0.9mm body steel, from the underside of the chassis. Then make a new hole for the piping around 3.5" and slightly forward as it seems to be rubbing on the front section. test fit to make sure all is smooth and no fouling.

Then, i would paint both sides of the patch with an etch primer then some chassis black paint.

get some cardboard and trace out a piece that will cover the battery tray right the way under the guard mount, all the way to the wheel well and back to the chassis rail towards the centre of the car.

Use that piece to cut out a Flat sheet of 2mm polished alloy so you can cover the entire area. mount that with screws into teh old tray. then you can cut a matching hole in that from underneath to match the bottom hole.

use that alloy sheet to remount those wires, install a catch can, radiator over flow.... etc etc etc

------------------------------------

If you want it done as cheap as possible, you could follow the above, then cut out your patch panel and the patch, needs to me no more than 1mm gap all around, then just take it somewhere to get tig welded up, might cost you $50 to weld it depending on how good your cutting and patch is.

      For sure the later RB26 variants had a different setup (6 cam voltage sender?), but the RB25DE/DET share the same ECU pinout/PCB footprint, and at the ECU plug it ends up being 'throttle sensor in' & 'throttle sensor out' (to A/T TCU) ...you stick a multimeter on these pins and you'll find them directly connected (0 ohms) ; I had an pair of Nissan ECUs on the bench long ago, and I noticed this throttle sensor in/out link, actually linked to an op-amp ...which was unpopulated on the NA board, but present on the T board and I went 'ah-ha!' in some moment of clarity... ...it wouldn't surprise me if they changed strategy here though (in the software and actual monitoring of this signal), because they did with other stuff (A/T signals).. and 0.45v as a trigger point makes sense, as that's what the external TCU units expect at idle ; kudos, thanks for that insight...I suppose it boils down to whether or not Consult can display real time data of that signal's voltage... ...in any event, it presents the same target...ie; rotate TPS unit to achieve 0.45v to suit both ECU&TCU, and where do you goto from there? Just disconnect TPSwitch connector and/or that plus TPSensor connector....or do you go for the throat and disconnect IACV solenoid and see if it still stalls? (probably throws a recoverable fault code and goes for default idle strategy?)...

      I’m also conscious that e85 is slowly being phased out. Not all United’s have them anymore. Can’t take the risk of being low on petrol and assuming the servo will have it.

      MR HAMMER has said his piece. Painted up to avoid Rusty Rusty. Actually lines up well. (i.e it lines up the same as the unmolested GTR guard). Turns out the GTR Strut brace does foul on the bonnet vents ever so slightly. May need a little bendy bendy if intended to keep using with a strut brace. So spacing it out to clear the FAST102 is not an option. Annoyingly, the bonnet vents also foul on the heater lines running over the engine. Given this engine does not EVER require a heater, a delete loop is going to be used. Don't worry, the defogger uses the AC. The heater is basically "Do not use the aircon and turn the fan on". It will still be effective, I promise.... once I get the system regassed... Will have to revisit with unvented bonnet I suppose, and suitable strut brace. There's plans to do this and other things tonight and bleed brakes (there was a weep) and put the bumper back on, and take Good Friday morning - Because troubleshooting on the side of the road limping it home at midnight tonight is ... not very smart.
